Reaction Steps

2-(Ethylsulfonyl)-4-[m-(trifluoromethyl)benzyl]-6-[(α,α,α-trifluoro-m-tolyl)oxy]pyrimidine (0.40 g, 0.82 mmol) is added to THF (20 ml). Dimethylamine hydrochloride (0.11 g, 13.4 mmol) and triethylamine (0.17 g, 16.8 mmol) is added and the reaction stirred at room temperature for 18 days. Ethyl acetate is added to the reaction and the organic phase is washed with water, brine and dried over magnesium sulfate. The solvent is removed under vacuum and the residue is chromatographed to afford 0.40 g 2-(Dimethylamino)-4-[m-(trifluoromethyl)-benzyl]-6-[(α,α,α-trifluoro-m-tolyl)oxy]pyrimidine as a yellow oil. 1H NMR CDCl3 3.02 (6H, b) 3.92 (2H, s) 5.87 (1H, s) 7.3-7.65 (8H, m).
